A template SDL3 cross-platform project

You can find compiled binaries and a play-on-web version here: https://cheyao.itch.io/test-sdl3

SDL3 SDL3_image

git clone https://github.com/cheyao/TileMap
cd TileMap
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .

To make release on mac:

./mac-patch-dylib.sh

This will patch the binary to include SDL in the bundle

Compile and install SDL and SDL_image as you would but with emscripten. (You need static libs -DBUILD_SHARED_LIBS=OFF)

mkdir build && cd build
emcmake cmake -DCMAKE_BUILD_TYPE=Release ..
emmake make 

When building there should be errors saying for example that you need png library, so go to the external folder of SDL_image, run ./download.sh and go to the directories of the missing libraryies and build with cmake & emscripten.

export CFLAGS="-m32"
export CXXFLAGS="-m32"
export LDFLAGS="-m32"
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .

To distribute on linux you can use

./cmake/distribute-linux.sh

The output will be in output

mkdir build && cd build
x86_64-w64-mingw32-cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .

See https://cheyao.github.io/cross-compile-windows.html

mkdir build && cd build
source ~/emsdk/emsdk_env.sh
emcmake -DCMAKE_BUILD_TYPE=Release ..
emmake

See https://cheyao.github.io/cross-compile-web.html

git submodule update --init --recursive
cd android
./gradlew build

You will find an unsigned apk in app/build/outputs/apk/release/

You can sign the app with cmake/sign-apk.sh, just edit it with your env variables
